ESC [ blah; blah H are cursor steering commands.
ESC [ 2 J is a screen clear command
ESC [ ? 3 l is likely the mode change, but I can't check
now (I'm abroad).

It is almost as if the commands are damaged coming in. Printing
and screen width changing, and such, do work fine with MSK. I suggest
some additional session logs if you can, and I can look at things when
I get back in the States in the middle of August.
